Police say an Uber Eats food delivery driver accused of fatally shooting a customer in Atlanta is in custody.

Local media report 36-year-old Robert Bivines turned himself in Monday, according to the Associated Press. Atlanta police said in a statement they had a warrant charging Bivines with felony murder.

The Atlanta Police Department confirmed to NPR that officers responded to a call of a person shot in the Buckhead neighborhood in North Atlanta on Saturday around 11:30 p.m. Investigators learned from witnesses that the victim left his apartment to meet an Uber Eats driver, took his order and began walking away from the delivery vehicle.

Words were exchanged between the victim and the delivery driver as the victim walked back to his apartment. The driver fired several shots from his car, striking the victim multiple times. The driver fled in a white Volkswagen, according to reports.

The victim was transported to Grady Memorial Hospital in critical condition,and later died from his injuries.

Bivines’ attorney, Jackie Patterson, told WSB-TV his client “had no choice but to defend himself” when the man became irate and aggressive over his order, according to AP.

The Fulton County Medical Examiner’s Office identified the victim as Ryan Thornton, 30, of Atlanta, according to NBC’s WXIA. Thornton’s family told the local NBC affiliate that the victim had graduated with a degree in political science from Morehouse College in May, and recently started a new job.

Uber Eats is a food delivery service provided by Uber. Using the Uber Eats app, customers can order food directly to their homes in 37 North American cities. Couriers can deliver orders by foot, bikes or cars, and customers can track couriers’ locations the same way that they track the locations of Uber drivers.

“We are shocked and saddened by this news,” Uber spokesperson Andrew Hasbun told NPR. “We are working with the Atlanta Police Department, and our hearts go out to the families of those involved.” The spokesperson added that Uber will say more when an arrest is made.

According to Uber, its driver prescreening includes a review of motor vehicle records and a search through criminal records at the county, state and federal levels. It’s also against company policy for drivers to carry firearms of any kind while using Uber apps.

It is unclear how Uber monitors this policy.

In 2016, Uber driver Jason Dalton committed a series of seemingly random shootings in between passenger pickups in Kalamazoo, Mich. None of Dalton’s passengers was physically harmed. At the time, Uber defended its background check process, saying that no screening would have flagged Dalton, who had no previous criminal record.
